SPECEFICATION forming part of Letters Patent No. 3424,731, dated June 29, 18186.

Application filed March 25, 1886.

To all whom it may concern.-

Beit known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Sheet-Delivery Apparatus for Printing-Machines, of which the following is a specification.

My invent-ion relates to improvements in sheet-delivery apparatus for printing-presses, and especially for stop-cylinder presses; and it consists, essentially, in an eccentric carrierreel, which is adapted to receive the printed sheet directly from the impressioli-cylinder and deliver the same, when thrown about its bearings, upon a receiving-table located in the press-frame. The carrier-reel is actuated to deliver the sheet at proper intervals by levers in connection with a cam on the main shaft of the press.

The y specific construction of my sheet-delivery apparatus is more fully pointed out in the following specification and claims, and illustrated in the accompanying` drawings, in which- Figure l represents a side elevation of a stop cylinder press provided with my improved sheet-delivery apparatus. Fig. 2 is an end elevation, partly in section. Fig. 3 is a vertical section n the plane :c m, Fig. 2, ofthe carrier-reel and its carriage, said figure being drawn to a larger scale than the preceding figures. Fig. 4 is a similar section in the plane y y, Fig. 2.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the press-frame constructed to support the impression-cylinder B and the type-bed C in the proper relation to eachother. At one end of the press-frame are bearings for the drivingshaft D, from which motion is transmitted by gear-wheels D D2 to the main shaft E of the press, from which motion is in turn transmitted by the usual crank, E, and connecting-rod F3, Fig. 1, to the traveling cog-wheel E, which meshes into a stationary rack, Et, on the base of the press, and also engages asuitable rack, FP, pendent from the type-bed C, whereby a reciprocating motion is imparted to the typebed. The impression cylinder B receives its Serial No. 196,559. (No model.)

motion from the type-bed C through a second rack, C', thereon, which is suitably arranged upon the latter to engage with the cog-wheel B', Fig. 2, of theimpression-cylinder. Aportion of this cog-wheel B is cut away, so as to permit the typebed C to travel while the cylinder is at rest during stated intervals. At a point back of the space in the cog-wheel B the imp ression-cylinder carries a toothed sector 0r catch, F, which is engaged by a catch-lever, 5o F, that operates to check, hold, and start the impression-cylinder under the impulse of adjusting mechanism ofwell-known construction. In the example shown in the drawings, this catch-lever is pivoted at j' to the press-frame 65 and is vibrated by means of a cam, F2, which has a suitable way therein, and a slotted rod, El, that is connected at one end to the catchlever, and on its other end is a roller-stud, f, which engages with the way in the cam. 7o

The impression-cylinder is provided with grippers B2, llig. l, for grasping, holding, and releasing the sheet. rglhese grippers are opened by trip cams B3 and Bt, arranged upon the press-frame in the proper relative positions, and they are closed by a spring, as usual, the whole constituting the main featuresof a stoprevolutionpress of well-known construction. To adapt my sheet-delivery apparatus to such a press, the impressioncylinder B is pro- 8o vided with an additional gear-wheel, Cr, which imparts motion to a gear-wheel, I, that is tightly. mounted upon a shaft, I, the latter having suitable stationary bearin gs in the press-frame.` Upon the shaft is mounted a circular disk or S5 wheel, l2, Figs. 2, 8, and 4, for a purpose to be hereinafter described. The shaft I', the gear-wheel I, and the disk I serve to support an eccentric reel, J, and are hereinafter collectively designated the reel- 9o support.

rlhe carrier-rcel J ,which delivers 'the sheets to a table, S, consists of two sectoral disks, J J2, which are eccentrically mounted at j j to a shaft, J3, having bearings at one end in the gear-wheel l, while its other end is supported in the disk l2. The apices of the triangular open spaces formed in the disks J JZ are rounded to `form a center which fits the diameter of the shaft l of the reel-support, so that 10o when in their normal position, Figs. 1, 3, and 4C, said disks rest with their centers upon the shaft of the reel-support and participate in the rotation of said reel-support.

To grasp the printed sheet as it is delivered to the carrier-reel from the impression-cylinder,to retain the same,and to release it when the carrier-reel is to be carried to its delivering position, I make use of grippers L,which are arranged on a horizontal gripper-shaft, L, that extends between and has its bearing in the gear-wheel I and disk I2 of the reel-support. The free ends of the grippers impinge upon a base, L2, that extends between and is secured to the gear-wheel I and disks I2, and the edge of the sheet is held between said base and the grippers. The end of the grippershaft L extends through the gear-wheel I, and a lever, Z, is secured thereto, one arm of which is subjected to the action of a spring, Z, while 'the other arm carries a pin, Z2, that is brought in position at the properintervals to be engaged by the face of a tripcam,M,secured to the pressframe. The action of the spring Z tends to close the grippers upon the sheet after the lever Z is released.

To trip the sectoral -disks J J2,constituting the eccentric carrier-reel,theshaft J2 on which these disks are mounted is provided with an arm, N, which is acted on by a suitable lever actuated from the main shaft E of the press. In the example shown in the drawings I use a bell-crank lever, N N2, which is pivoted at a to the press frame. One arm of this lever is in contact with the arm4 N of the rock-shaft4 is connected with the arm of the rock-shaft J2,

which spring returns the reel-carriage to the position shown byV full lines in Fig. 1-that is to say,\its receiving position-whenever the same is thrown about its bearings by the lever N N2.

As before described, the eccentric carrierreel J is connected with the reel-support by the shaft J3,and consequently when the reel is in its receiving position it rotates with the reel-support to receive the sheet. Owing to this connection it is necessary thatthe carrierreel should be actuated to deliver the sheet at those intervals in which the cylinder is at rest, and consequently the reel-support is not rotating. This is done by the proper contour and throw of the cam N3. The lever N N2 is so arranged that it will not interfere with the rotation of the carrier-reel when the latter is receiving the sheet.

The operation of the delivery apparatus is as follows: In the drawings the working parts of the press are shown (by full lines) in the position they will be in when the press has finished printing a sheet, in which position the impression-cylinder is in such a position that the grippers thereof are ready to grasp This latter arm of the lever car` the next sheet as it is fed forward from the delivery-table and a sheet is under the grippers of the reel-support. As the main shaft E now continues its motion in the direction indicated by arrow l, Fig. l, the type -bed C moves toward the impression-cylinder Bin the direction of arrow 2, marked thereon in Fig. l, but does not rotate the impression-cylinder, since the latter has not yet been shifted by the catch-lever F', so as to bring its teeth in the proper position to be engaged by the rack C on the type-bed, and the impression-cylinder is not rotated until the' bed returns from its extreme position on the opposite side of the impression-cylinder. During this first half of the semi-revolution of the main shaft E and the corresponding traverse of the bed the cam N3, moving in the direction of arrow l, Fig. 1, engages the arm N2 of the lever N N2, and the eccentric carrier-reel is thrown about its bearings to its delivering position, as shown by dotted lines in Fig. l, and during the remainder of the semi-revolution of the shaft E the lever returns to its original position and the carrier-reel is drawn to its receiving position by the spring thereof. Just before the carrierreel moves from its receiving position to its delivering position above the receiving-table the gripper-lever Z comes into contact with the face ofthe trip-cam M and opens the grippers L ofthe carrier-reel, but the sheet clings closely to the disks of said reel until it is in its proper position over the receiving-table, at which pointthe sheet releases itself and falls, printed side up, on the table. During the remaining semi-revolution of the main shaft E the carrierreel J remains in its receiving position and rotates with the reel-support, which is now set in motion by the impression-cylinder, as the latter is now engaged by the type-bed which is moving toward its original position. As before stated, the carrier-reel is now rotating and the grippers L are held open by the cam M until the lever Z clears the cam, when they are closed; but at the same time the edge of the printed sheet is brought under the grippers L, and same is wound on the disks J J2. As the sheet is grasped by the grippers L, it is released by the grippers B of the impressioncylinder, said release being effected by the action of the cam B4.

Since the sheet is delivered to the carrierwheel J with its printed side facing toward the center of the reel,'it is necessary to use disks J J2, as shown, so that only the edge of the paper is brought into contact. The disks are made adjustable on the shaft J 2, in order to adapt them for varying sizes of sheets.
